The A4128 is a largely rural A-road in south Buckinghamshire. Originally the B483, it gained its current number in the late 1920s.
The road starts at a roundabout on the A413 Great Missenden bypass. It heads west into town, zigzagging across the old line of the A413 between adjacent mini-roundabouts. The railway line is then crossed and the road continues through the wooded western suburbs. Although this section of road is semi-rural it is never free from housing and we move seamlessly into the next village, Prestwood. The road runs along the High Street then bears sharply left to continue southwards.
Presently (after the A4128 appears to have spent as much time in Prestwood as is actually possible) the road enters open country. This doesn't last long as we soon skirt Great Kingshill. The next village is Cryers Hill, where we turn westwards once more and start to descend steeply - presumably this is the hill. At the bottom, in the Hughenden Valley, we reach a roundabout and turn left.
The road continues south along the valley bottom, the longest-lasting rural section on the whole road. Presently the road reaches the grounds of Hughenden Manor, formerly the home of Disraeli and now owned by the National Trust. On the far side of the estate we reach the edge of High Wycombe. The road enters town along Hughenden Road, which has a number of roundabouts. At one of these the road leaves its old route to follow a parallel D2 relief road. This goes under a railway viaduct before ending at a roundabout on the A40 by a shopping centre.
